Location: Tulsa, Ok | So I am just going to a jackpot for an evening. Batteries on trailer are fully charged. Not plugging in or running generator. Just occasionally using the amenities inside that will run on battery, maybe flipping on outside lights to unsaddle. How long (balllpark) should the battery power last? |

| They will for sure, last you through the evening. I'd guess they'd last a week, don't know how old the batteries are. |

| They should last a few days depending on how old they are , they should stay charged off your truck battery. |

| 5 days...ask me how I know lol
I took my trailer in on a Monday to have some work done last week. The fridge was running on gas but still needed the battery to light it. Most of the work was outside, but they probably had the lights on a few times.
I got there Saturday morning to pick it up and the batteries were 99% dead. No one was around...Did I mention my trailer has hydraulic jacks??? There was some anxiety, a little cussing, and eventually locating an extension cord and an outlet after calling over to the dealership.
So there you have it - with little use trailer batteries in good condition will last approximately 5 days. |

next time just back your truck up to it and plug the trailer plug into your truck.
If it's wired correctly you will have a 12v aux that will run all that stuff off your truck.

I have had to plug my trailer into the generator before just to get my hydraulic jack to work. LOL Mine died over night while I was staying with someone else. I probably left something on, but not for sure.
Bottom line they should be good for a few days at least with minor/moderate use of lights and such. |

Location: Smack Dab in the Middle | Your batteries should have a "reserve time" listed on them. I think mine are something like 125 hours at x volts...and then they should also have a time in months that they should hold a charge with no pull. All at new of course, and declining from there. |

| Be very very careful plugging into the truck without it being grounded on the ball. I always plug lights in LAST after trailer is hooked up. If its not wired correctly you could fry the power supply in your truck. Also, when at a race or parking for a while UNPLUG the trailer from the truck. Most will drain the truck battery before they drain the onboard trailer batteries. Go to leave and truck won't start! |

Not if the battery is dead.
And we don’t have turnip trucks where I come from, we have tomato trucks... |

Location: Tulsa, Ok | Thanks for the replies. My husband insists the battery power on the trailer does not last as long as it should. Not really sure how he has reached that conclusion, because he NEVER goes with me and hence has no clue when or if the power drains. We had to replace a battery today because it had a bad cell and I think he wanted me to feel bad.
I however just laugh because everyone know if something breaks in possession of the wife it is always her fault. If it breaks in possession of the husband it is because the item in question is a piece of chit!! |

| She was nicely trying to give you helpful advice. She didn’t accuse you if being stupid..i.e. falling off the tomato truck. A simple thank you would have been a more appropriate reply. |

The truck n stuff place did not run a hot wire to mine either. Dealership took mine in. Guess they did not know it was necessary and apparently thought my trailer was just a cattle trailer. Who knows. This is NOT uncommon. Annoying,yes. |

Location: North Dakota | I've done weekend barrel races Friday morning-Sunday afternoon in the winter, running my fridge and heater off just the battery and it has not died on me. I left the trailer plugged in with my fridge on, until I hooked up. This way the fridge was using electric and not propane to cool down before I left, and therefore used less propane during the weekend. I also turn the heat way down/off during the times I know I won't be in the trailer for awhile. |

| I get about 2 days out of mine until I have to recharge. That's obviously not leaving lights on but simply turning on or off for short use.
If I run the furnace I can get about 8 hours.
